I can not, for the life of me, get even one of the four retaining bolts at the rear of the driveshaft to come loose. For three days I have been hitting them with pb blaster and alternating between using two long handled wrenches, socket wrenches, and an impact driver with no luck. I'm trying to replace the rear pinion seal and put an end to the rear differential leak I've been experiencing, but I can't get in there to do it! Anyone have a trick that breaks stubborn bolts like these ones loose? I'm limited with how much leverage I can get because I'm doing this job on the ground in the driveway. I tried the double wrench trick but it did not work. Hoping there is a MUD trick out there that will help me out.
Edit: Also not really keen on the idea of using a blow torch down there to heat up the bolts. Just seems like a bad idea to me.
